Reliable PHP Development for Web Apps, APIs and CRMs
PHP powers a large share of the web, including WordPress, Laravel and many open-source CRMs.
Xirgosoft builds custom PHP applications and APIs, upgrades older PHP code to current versions and extends PHP-based systems such as vTiger and SuiteCRM.
We write clean, secure, maintainable code and document it so your team can keep building.
PHP Development Done Properly
PHP powers a large part of the web, including WordPress, Laravel and many CRMs such as vTiger and SuiteCRM. Modern PHP is a very different language from the PHP of ten years ago: it has strong typing, attributes, enums, better performance and a mature ecosystem with Composer and widely adopted standards.
We write PHP the modern way. That means clean structure, dependency injection, automated tests where they add value, static analysis, careful input validation and secure handling of sessions, passwords and file uploads. We build custom web applications and APIs, extend CRM systems with modules and integrations, and help teams maintain code they have inherited.
A common request is upgrading older applications still running on unsupported PHP versions. We assess compatibility, fix deprecated code, update dependencies and test thoroughly, so you can move to a supported version and reduce security risk. We document what we change and provide a clear handover, so your team is never locked into us.

Frequently Asked Questions
Which PHP versions do you work with?
We build on current supported PHP versions and can upgrade older applications.
Can you fix or extend our existing PHP site?
Yes. We start with a code review and recommend the safest path.
Do you use frameworks?
Usually yes. Laravel is our default for new applications.
Can you extend vTiger or SuiteCRM?
Yes. Both are PHP-based and we build custom modules and integrations for them.
Can you help us decide between upgrading and rewriting?
Yes. We review the code, test coverage and business risk, then recommend an upgrade, a gradual refactor or a rebuild, with the cost and trade-offs of each.
Do you write automated tests?
Yes, particularly around critical business logic and code we are refactoring, so changes can be made safely.
How do you handle security in PHP applications?
We validate and escape input and output, use prepared statements, manage sessions and passwords properly, restrict file uploads and keep dependencies updated.
Can you document and hand over the code?
Yes. We provide documentation, set-up instructions and a clean repository so your team can continue independently.
